98, 95% confidence interval [CI] 1.01-3.90), use painkillers prior to treatment (OR=2.52, 95% CI 1.33-4.77), and have more pre-treatment anxiety symptoms (OR=1.26, 95% CI 1.15-1.38).

Unfavorable sleep quality trajectories are prevalent among HNC patients from pre-treatment to 6-month after treatment. A periodic sleep evaluation starting shortly after HNC diagnosis is necessary to identify persistent sleep problems, especially among high-risk group.

Mucoepidermoid carcinoma (MEC) is the most common type of salivary gland malignancy. Advanced or high-grade MECs are refractory to chemotherapy, often leading to tumor recurrence/metastasis and abysmal~35% 5-year survival. Causal links have been established between Epithelial Growth Factor Receptor (EGFR) activation and poor outcome. Herein we investigated the therapeutic efficacy of EGFR inhibition against MEC using in vitro pre-clinical models.

Five human MEC cell lines were used in cell viability, cytotoxicity, apoptosis, cell cycle, 2D-clonogenicity, and 3D-spheroid formation assays following treatment with Erlotinib (EGFR inhibitor), SAHA (Histone Deacetylase inhibitor; HDAC) and CUDC-101 (dual EGFR-HDAC inhibitor). Effects on MEC cancer stem cells were evaluated using flow cytometry. Gene expression and pathway regulation were evaluated via qPCR and Western blot, respectively.

MEC cells enter a quiescent, non-proliferative yet rapidly reversible drug tolerant state upon EGFR inhibition. Despite rothe applicability and efficacy of dual EGFR-HDAC inhibitors for the clinical management of MEC.

Over the last few decades, there have been changes in the diagnostic capabilities and treatment of head and neck squamous cell carcinoma (HNSCC) patients. However, the impact of these changes on the ultimate survival of patients remains unclear. The objective of this study was to analyze the changes in disease-specific survival of patients with HNSCC treated consecutively over a period of 30years in a tertiary center.

We carried out a retrospective analysis of 5,206 carcinomas located in the oral cavity, nasopharynx, oropharynx, hypopharynx, larynx or with metastatic squamous cell carcinoma without a known primary tumor treated in our center during the period 1985-2016. The overall and disease-specific survival was analyzed according to the year of diagnosis of the tumor.

There was a significant trend towards an increase in disease-specific survival over the study period, with an average survival gain of 0.28% per year, which means an increase in 5-year disease-specific survival values from about 63.5% during the initial years of the study to 72% during the final years. Patients who had a greater increase in survival were those with primary tumors located in the rhino-oro-hypopharynx, with advanced tumors (stages III-IV) and treated with radiotherapy or chemoradiotherapy. This increase in disease-specific survival did not translate into overall survival.

Over the last 30years we have observed a significant increase in the disease-specific survival of the patients with HNSCC, with an average increase of 0.28% per year in the 5-year specific-disease survival.

The importance of treating the bilateral neck in lateralized small oral cavity squamous cell carcinoma (OCC) is unclear. We sought to define the incidence and predictors of contralateral neck failure (CLF) in patients who underwent unilateral treatment.

We performed a multi-institutional retrospective study of patients with pathologic T1-T2 (AJCC 7th edition) OCC with clinically node negative contralateral neck who underwent unilateral treatment with primary surgical resection±adjuvant radiotherapy between 2005 and 2015. Incidence of CLF was estimated using the cumulative incidence method. Clinicopathological factors were analyzed by univariate (UVA) and multivariate analysis (MVA) for possible association with CLF. Kaplan-Meier analysis was used to estimate overall survival (OS).

176 patients were evaluated with a median of 65.9months of follow-up. Predominant pathologic T-stage was T1 (68%), 8.5% of patients were N1, 2.8% were N2b. Adjuvant radiotherapy was delivered to 17% of patients. MS4078 5-year incidence of CLF was 4.3% (95% CI 1.2-7.4%). Depth of invasion (DOI)>10mm and positive ipsilateral neck node were significant predictors for CLF on UVA. DOI>10mm remained significant on MVA (HR=6.7, 95% CI 1.4-32.3, p=0.02). The 2- and 5-year OS was 90.6% (95% CI 86.2-95.0%) and 80.6% (95% CI 74.5-86.8%), respectively.

Observation of the clinically node negative contralateral neck in small lateralized OCC can be a suitable management approach in well selected patients, however caution should be applied when DOI upstages small but deeply invasive tumors to T3 on 8th edition AJCC staging.

Since the standard of care for treatment, which includes surgery and chemoradiation, has not provided a sustainable and durable response in affected patients, seeking novel therapeutic approaches to treat GBM seems imperative. Immunotherapy, a breakthrough for cancer treatment, has become an attractive tool for combating cancer with the potential to access the blood-brain-barrier (BBB). In this regard, programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1), as major immunological checkpoints, have drawn considerable interest due to their effectiveness in a spectrum of highly-aggressive neoplasms through negative regulation of the T-cell-mediated immune response. Nevertheless, due to the immunosuppressive microenvironment of GBM, the efficacy of these immune checkpoint inhibitors (ICIs), when used as monotherapy, has been unfavorable and lacks sufficient beneficial outcomes for GBM patients. A variety of clinical studies are attempting to evaluate the combination of ICIs (neoadjuvant/adjuvant) and existing treatment guidelines to strengthen their effectiveness; however, the exact mechanism of this signaling axis affects the consequences of immune therapy remains elusive. This review provides an overview of the PD-1/PD-L1 pathway, currently approved ICIs for clinical use, preclinical and clinical trials of PD-1/PD-L1 as monotherapy, and when used concomitantly with other GBM treatments.COVID-19 is an acute respiratory syndrome caused by SARS-COV-2 which has now become a huge pandemic worldwide. The immunopathogenesis of COVID-19 has been established that increased serum levels of C-reactive protein (CRP), interleukin-6 (IL-6), and reduction of the CD4+ and the CD8+ T lymphocyte populations, are the most reported immunological findings in these patients. High levels of other inflammatory cytokines and chemokines such as IL-2 and IL-8 with an increased number of neutrophils and eosinophils may induce immune abnormalities in patients with COVID-19. There is growing evidence to obtain a deeper understanding of the immunopathogenesis of COVID-19 which will lay the foundation for the development of new potential therapies. However, specific and non-specific immunotherapies such as convalescent plasma (CP) are widely performed to treat patients with severe COVID-19, there is no definitive evidence to suggest the effectiveness of these treatments. Hence, this review aimed to highlight the current and most recent studies to identify the new immunotherapeutics for COVID-19 disease.

Anti-tumor necrosis factor-alpha was regarded as an option in treatment of non-infectious uveitis. However, few studies in the far easter region have concentrated on this therapy and current studies have not emphasized the elimination of retinal vasculitis. To compare the effectiveness of adalimumab (ADA) plus conventional therapy (CT) versus CT alone in treating patients with retinal vasculitis (RV) due to refractory Behçet's uveitis (BU).

Retrospective cohort study.

Clinical records of BU patients with previously treated but poorly controlled RV were analyzed. Patients were allocated into two groups depending on ADA use. Each group was treated for no less than 6months between February 2015 and September 2020. The primary outcome parameter was the RV score. Best-corrected visual acuity (BCVA), number of relapses, macular thickness and ocular complications were considered concomitantly.

Forty-two patients (72 eyes) were included; 21 patients were in CT group, and 21 patients were in ADA group. Inflammatory parameters improved in both groups. The improvement in the fluorescein angiography (FA) score and anterior chamber inflammation were significantly better in ADA group than in CT group (P<0.05). The relapse time was significantly lower in ADA group than in CT group (P=0.01). Daily glucocorticoid dose tapers were more evident in ADA group than in CT group (P<0.05). Adverse events were detected in 7 patients (5 had upper respiratory tract infection and 2 had gastrointestinal discomfort) in ADA group; in CT group, upper respiratory infection and recurrent gum swelling were observed in 1 patient each.

Our results indicate that ADA plus CT outperforms CT alone in patients with RV due to refractory BU. More agile ADA use in these patients should be considered to achieve optimal treatment.

Approximately 10-15 % of cancer cells use a homologous recombination-based mechanism known as the Alternative Lengthening of Telomeres (ALT) pathway to maintain their telomeres. Telomeres in general pose a challenge to DNA replication owing to their repetitive nature and potential for forming secondary structures. Telomeres in ALT+ cells especially are subject to elevated levels of replication stress compared to telomeres that are maintained by the enzyme telomerase, in part due to the incorporation of telomeric variant repeats at ALT+ telomeres, their on average longer lengths, and their modified chromatin states. Many DNA metabolic strategies exist to counter replication stress and to protect stalled replication forks. The role of proliferating cell nuclear antigen (PCNA) as a platform for recruiting protein partners that participate in several of these DNA replication and repair pathways has been well-documented. We propose that many of these pathways may be active at ALT+ telomeres, either to facilitate DNA replication, to manage replication stress, or during telomere extension. Here, we summarize recent evidence detailing the role of PCNA in pathways including DNA secondary structure resolution, DNA damage bypass, replication fork restart, and DNA damage synthesis. We propose that an examination of PCNA and its post-translational modifications (PTMs) may offer a unique lens by which we might gain insight into the DNA metabolic landscape that is distinctively present at ALT+ telomeres.
